Capcom.They really care about their fans. Look at the anime Sengoku Basara and Devil May Cry. If they weren't involved certain voices would not have appeared in the anime.

Crapcom cares about there fans? Gonna have to disagree with you there. Alot of Devil May Cry fans want a sequel to Devil May Cry 4 and plead Crapcom to due so... but what do the DMC fans get instead? reboots version of DmC. Now, Im gonna talk about how Crapcom abuses the DLC, putting alternate costumes and character content as DLC that should of been "in disc" already.

Crapcom = Activision

SquareEnix? Well after Squaresoft merged with Enix, there quality of their games been lacking and most of their games were avg.

In all I would have to say Naughty Dog, with Uncharted 3 coming out they know how to listen to the fan base, unlike majority of Japanese gaming companies.

not an option here but it should be: Valve
they brought us the Half Life series, critically some of the best games out there
the newly released Portal 2, sequel to the ground breaking Portal
and the brilliant Team Fortress 2 and Left for Dead series
every single game of theirs is brilliant
